To all whom it may concern:

Be it known that I, VV'ALTER Ri'iBnL, a

subject of the-Emperor of Germany, residing at. Berlin, Germany, have invented a new and useful Alloy, of which the following is a specification.

'This invention relates to an improved iron nickel aluminium manganese alloy, which is adapted to be mixed with metals to form other alloys, for example, it may be mixed with copper and aluminium to form a bronze.

According to the invention, iron,nickel, manganese, and'aluminium are melted .together in proportions corresponding to the multiples in the following formula, viz:

. 4(FeNi)+8A1-l-Mn.

Thus v 4(55.9 +58.6)+8 27.02+55 gives the following percentage composition: iron 30.67, nickel 32.14, aluminium 29.64,

7 .541. Small variations from the above propor- Specification of Letters Yatent.

of their atomic weights, expressed Patented @ct. animal Application filed June 23, 1913. Serial No. 775,353.

tions can be made, for example, an alloy having the following-composition has been found to give good results: 31 parts by weight of iron, 32 parts by weight of nickel. parts by weight of aluminium; 7 .5 parts by weight of manganese.

What I claim is:

1. An alloy consisting of iron nickel, manganese and aluminium melted together in proportions corresponding to the multi les of their atomic weights expressed in the following formula, viz:

2. An alloy consisting of the following metals melted together in the following proportions by weight, viz :iron 31 parts, nickel 82 parts, aluminium 30 parts and manganese 7.5 parts.
